This study shows that cocaine strengthens glutamatergic transmission, reduces K+ channel function and drives hyperexcitability in lateral habenula neurons projecting to the rostromedial tegmental nucleus. The authors also show that GluA1 trafficking mediates these cellular modifications and is instrumental in a drug-mediated depressive-like phenotype.
